Title: Dispositif pour pedalier
Inventor: JACQUES ANDRE
IPC: B62M1/36
Filed: 1999-11-03
Abstract: Pour comprendre cette invention, il faut commencer par comprendre en profondeur la découverte suivante qui concerne le mollet quand on appuie sur  une pédale, deux illusions d'optique trompant le monde entier (les fig 21 et  22 symbolisent un membre inférieur appuyant sur une pédale, (6) étant la cuisse, (11) la jambe, A+B le pied et (1) la cheville). La 1ère illusion (fi g 21) est de croire que le mollet (M) augmente la pression sur la pédale. La deuxième illusion (fig 22) est de ne pas voir la force M' qui annule la forc e M. La totalité de la pression sur la pédale provient de la cuisse seulement,  la contraction du mollet étant une perte d'énergie. L'invention consiste à remplacer la pédale par un mécanisme permettant d'éviter l'usage du mollet c e qui multiplie par deux le rendement sans perte de puissance.
